IBM Enterprise Workload Manager Release 1

120 IBM Enterprise Workload Manager

5.1 Overview of the process

Before building your domain policy you need to carefully assess your environment and plan

your EWLM setup. As with the workload management functions of individual operating

systems, the planning and preparation phase is the most important step to successfully use

workload management capability. You need to collect information from various EWLM domain

resources and decide what needs to be monitored.

The purpose of this chapter is to present an example implementation of EWLM and to give an

explanation of some of the main considerations for designing and building it. The following list

describes our five phase approach to building an EWLM domain. The goal of these steps is to

produce a representation of EWLM domain policy with a measurable business goal that is

easy to understand and that will serve as a basis for future expansion. These steps may not

be a linear process and you may need to move several times between steps three and five.

1. Assessment

a. Defining the EWLM domain

b. Identifying all servers and middleware

c. Identifying all applications

2. Planning

a. Naming the domain policy

b. Defining the user information

c. Defining the directory and port configuration

3. Design

a. Identifying the transactions that request business functions

b. Identifying the processes that request business functions

c. Grouping service classes into a workload

d. Setting service class goals

4. Classifying the work

a. Defining classification filters for each transaction and process class

b. Creating the domain policy at the EWLM Control Center

5. Verification

a. Verifying transaction request classification filters

b. Verifying service class definition

c. Defining and implementing service policy

In addition, we include some information on monitoring and reporting functionality once you

have set up your EWLM domain. This includes reports and monitors which can help you

understand and diagnose performance problems you may have or suspect in your

environment.

We provide many tables which you can use to collect information when you organize your

EWLM domain. To collect this information you need to contact various people from your

company. This includes application designers, application developers, operations, system

administrators, and persons who are responsible for particular component monitoring. These

tables may be interim steps or they may be the final definition of your domain policy.
